The selection of the pouch requirements (1)
1. Selection of tooling
Pouch-making equipment includes specification board, heat seal knife, punch, special cutting knife, etc. Before production, it is very necessary to define the specific form of pouch-making, such as three seals and back seals, and then select the appropriate tooling to ensure the feasibility of the tooling.
Tooling is generally regulated according to the size of the product. For example, the specification board can be selected according to the width of the molding pouch; The heat sealing knife is selected according to the size of the heat sealing, according to the width of the heat sealing, the thickness of the material, the material is different, and the different forms of the heat sealing knife are selected in order to receive the best heat sealing effect; Punching machine according to the shape of the hole, choose direct pouch punching or punching processing.
2. Sealing position and cutting position
Sealing and cutting position seem to be very simple things, but often because of the assumption of mass product loss. Before starting the machine, the production order must be carefully reviewed, and the sealing position and cutting position of the pouch must be clearly defined. The sealing and cutting position of the pouch with a pattern or cursor are generally determined according to the pattern or cursor, such as the sealing or the back cover, under the cursor or the cursor, etc. For the product with irregular pattern, it can be defined according to the important mark in the graph. General sealing and cutting position is closely linked, but sometimes not completely unified, some special products must be examined carefully, so as to avoid cutting errors.
